I bought a few chassis on ebay a few years ago and this was one of them...I asked the seller and he was active in the early seventies, this may be a PARMA, anyone out there know and why does it pivot at the front axle...for little reason ?
I also have one believed RIKO that is mainly of wire, plated and inline with non revolving front axles....formula one ?...ken

Hi
I am pretty sure it is a demon chassis which has been used in the BSCRA production class
More 1980s/90s than 70 s

Cheers tony

Ta Tony....Quite an historic piece then?

but why does the rear end "steer"...ken

The simple answer about the pivot is because the chassis works better like that. I've see many attempts at a deeper explanation as to why, none of them terribly convincing.
Having the pan section moving separately can give much better handling than a one piece chassis. Mostly of the best designs have a pivot or very limited movement at the front and considerably more up and down movement at the rear. How to make this work best has been the subject of much development and what look like minor changes sometimes give surprisingly large improvements in handling.

I've not seen a chassis quite like that before. It wouldn't require expensive press tools to make, so it may have been made in quite small numbers. Some parts of the design look quite Demon like and not much like a Parma. However, it's quite a bit different from the Demon chassis used in the BSCRA production class

(I've tried to add a picture of a Demon chassis, but it seems a bit hit and miss if it displays)

Ey Up,

Tony, certainly looks a bit like a Demon, but isn't, could be earlier, maybe "Wonderland" ??, ( note the steel angle-winder spur ), but there is something missing,
what holds the two halves together ??.

Someone has cut away the top of the "lugs" on the centre section through which the axle should pass !!.

"DR", This was a basic, cheap (!!) class to encourage more ECRA/BSCRA members. Chassis design quite simple, but even so could be made to go very well !!.

The body pan was hinged on the front axle to promote simplicity, whilst still allowing the necessary movement. The "tongue" at the back limited that movement.

good stuff friend, and even more research needed...what is the pic you added? please..ken

 

[dragracer]

There are no cuts and the chassis has no problems tho' the motor screw holes look slotted?...I was wondering ifthe wheelbase was adjustable as there are 3 sets of front axle holes!..k

 

[dragracer]

this thing is growing on me...ken

 

[dragracer]

still looking and I see that the rear does not pivot on front axle, but a pin running beneath the front axle!

 

[dragracer]

found this, the seller atthe time thought a parma...

Hi Ken
The chassis were all for 1/32nd scale although as I put in the add that the Parma chassis was used by me for a !/24th Scale Mini

This is an Italian production chassis from the late 80's, think it was called Hobbymodels.
I had one of these and ran it at NLondon in early production race club nights many years ago, now chopped and converted into a CSCRA sports car!
This chassis was a follow on from the Tover cars and could well be the daddy of the Demon chassis, it's possible Joe Montiglio designed them both.
Your chassis seems to be complete and with a Wasp motor should go quite well, any Betta body will fit and yes you can adjust the wheel base.

Yes it does - that looks very similar to how the Demon pivot works - could be John is right about it being the daddy of the Demon chassis
Parma used the front axle as pivot for the pans.
Maybe that was one reason why the Demon worked better.
